IMPROVEMENT lN APPARATUS FOR REMOVING CARD-TEETH.

Specication forming part of Letters Patent No. 196,133, dated October16, 1877; application filed September 26, 1877.

To all whom it may concern Be it known that I, ALBERT A. BRAOKIETT,

. of Milton, in the county of Norfolk and State of Massachusetts, haveinvented certain Improvements in Apparatus for Removing the Teeth ofCard-Clothing from the backing thereof, of which the following is aspecification:

In the accompanying drawing, forming a part of this, specification,Figure l represents a side view of an apparatus embodying' my invention.Fig. 2 'represents a top view of the same. Fig. 3 represents a sectionon line x m, Fig. 2. Figs. 4 and 5 represent portions To this end myinvention consists, first, in a rotary comb composed of a cylinderhaving teeth which, on a line parallel with the axis of the comb, arearranged to correspond or register with the rows of wire staples formingthe teeth of the card clothing, whereby all the teeth in the samelongitudinal series are enabled to engage with all the rows of wirestaples on the back of the card-clothing, when the clothing is presentedto the comb diagonally to the axis of the latter.

' My invention consists, secondly, in the combination, with the rotarycomb, of devices for supporting and guiding the card clothing while itis being presented to the action of the comb, all of which I will nowproceed to describe.

In the drawings, A represents my improved comb, which is composed of acylinder having teeth c. These teeth are preferably arranged in a serieswinding spirally aroimd the cylinder, and in a number of longitudinalseries, the teeth composing the latter being arranged to correspond orregister with the rows of wire staples which form the teeth of ordinarycardclothing when said rows extend about at right angles with the axisof the comb, as shownin Fig. 4. b b represent the backs ofthe wirestaples which compose the teeth of the cardclothing c, these staplesbeing arrangedin rows extending diagonally across the strips of leatherinto which they are inserted, and the rows are separated by spaces b',which are equal in width to the length of said backs in a line parallelwith the latter, as shown in Fig. 4. The teeth'co of the comb are soarranged that all the teeth of each longitudinal series will come incontact with all the rows of wire staples of the card-clothing duringeach revolution of the comb, when the clothing is heldin substantiallythe position shown in Fig. 4- that is to say, with the sheet of clothingextending diagonally to the aXis of the comb, and the rows of staplesabout at right angles to the same. When the clothing is in thisposition, with the surface of its back parallel with the axis of thecomb and pressed against the teeth thereof, the rotation of the combwill cause each longitudinal series of teeth a to engage with each rowof the backs b of the staples or teeth, in such manner as to pull thestaples or teeth with great rapidity from the leather strip, the combbeing revolved at a high rate of speed. The rotation of the comb feedsthe clothing along as fast as the teeth are pulled out, and I have foundthat by passing a strip of clothing once under the comb the wire teethare all removed, and that the surface of the leather is uninjnred by thecomb, the teeth of the latter only touching the staples.

The comb Ais journaled in a suitable framework, and adapted to berotated in any desired manner. I prefer to apply the roll to the centersof an ordinary lathe, L, as shown in Figs. l and 2, the bed of the lathebeing preferably provided with certain attachments, to be de scribed.

For guiding and supporting the clothing while it is being acted ou bythe comb, I prefer to employ a board or rigid slide, c, which is adaptedto be moved along under the comb, and is provided with pins e', or otherdevices, for securing the card-clothing to its upper surface. f frepresent guides, which are connected to the bed of the lathe or frameL, de-

tachably or otherwise, and are diagonal to the axis of the comb A, asshown in Fig. 2. g represents a friction-roller, which is journaled inthe guides f at right angles thereto, and is therefore diagonal to thecomb A. The roller g supports the slide e between the guides f, and thelatter keep the slide in about the position shown in Fig. 2, as it ismoved along under the colub.

I prefer to make the slide e somewhat narrower than the space betweenthe guides, so that the operator can turn the slide laterally to someextent. The slide is, preferably, provided with a handle, h, for theconvenience of the operator.

In using the apparatus thus constructedthe operator secures a strip orsheet of card-clothing, with its back uppermost, on the slide e, thenplaces the slide 011 the roller g, between the guides, and grasps thehandle h. When ,the teeth of the comb A take hold of the backs of thewire staples of the clothing they rapidly draw the teeth or staples fromthe leather, throwing them outwardly, and drawing the slide along asfast as the surface of the leather is cleared of its teeth, the operatorhaving only to guide the slide along and tilt it on the roller g enoughto keep the surface of the clothing in the proper proximity to the teethof the comb.

I prefer to make the roll gtapering` in form,

so that it will incline the slide transversely, and thus hold it in suchposition that its upper surface will be parallel with the axis of thecomb along the line where the comb acts on the clothing.

The slide e may be arranged to be guided by suitable mechanism, insteadof by the hands of the operator, without departing from the spirit of myinvention.

I claim as my invention- 1. The rotary comb A, forremovingthe teeth ofcard-clothing, herein shown and described, provided with teeth a, which,onaline parallel with the axis of the comb, are arranged to correspondor register with the rows of wire staples forming the teeth of thecard-clothing, substantially as described.

2. In combination with the rotary comb A, constructed as described, theslide e, for supporting the card-clothing, the guides ff, and thefriction-roller g, said guides and roller being diagonal to the axis ofthe comb, and located 011 a stationary bed under the same,substauti'ally as set forth.

In testimony whereof Ihave signed my name to this specification in thepresence of two subscribing witnesses.

ALBERT A. BRACKETT.
